Metastatic renal cell carcinoma presenting as a circumscribed orbital mass

Abstract

Purpose: To report a case of renal cell carcinoma presenting as a well-circumscribed orbital tumor.

Methods: Retrospective interventional case report.

Results: A 60-year-old woman presented with proptosis of the left eye. Imaging showed a well circumscribed tumor in the region of the medial rectus muscle. Excision biopsy revealed a diagnosis of metastatic renal cell carcinoma that was confirmed on abdominal imaging.

Conclusions: Renal cell carcinoma can rarely present as a well-circumscribed orbital mass and should be included in the differential diagnosis of such lesions.
